7000b66f7e Remove QVector in the API of QRhiResource subclasses
Forcing users to go through a QVector, when in practice they almost
always want to source the data from an initializer list, a QVarLengthArray,
or a plain C array, is not ideal. Especially since we can reason about
the maximum number of elements in the vast majority of use cases for all
the affected lists. QRhiResource is also not copyable so we do not need
the usual machinery offered by containers. So switch to a
QVarLengthArray.

Note that a resource is not a container. The only operations we are
interested in is to be able to source data either via an initializer
list or by iterating on something, and to be able to extract the data,
in case a user wishes to set up another resource based on the existing
one.

In some cases a QVector overload is kept for source compatibility with
other modules (Qt Quick). These may be removed in the future.

Also do a similar QVector->QVarLengthArray change in the srb-related
data in the backends.

6f4aa54131 rhi: Add compute api and implement for Vulkan and Metal
D3D11 and GL (4.3+, ES 3.1+) will come separately at a
later time.

53599592e0 Introduce the Qt graphics abstraction as private QtGui helpers
Comes with backends for Vulkan, Metal, Direct3D 11.1, and OpenGL (ES).

All APIs are private for now.

Shader conditioning (i.e. generating a QRhiShader in memory or on disk
from some shader source code) is done via the tools and APIs provided
by qt-labs/qtshadertools.

The OpenGL support follows the cross-platform tradition of requiring
ES 2.0 only, while optionally using some (ES) 3.x features. It can
operate in core profile contexts as well.
